Key Error when trying to get header value
Question
I am just trying to request a form value in flask. Something i have done many times before with no issue but I cannot figure out why I am getting this key error.
I have tried many things like switching from a get request to a post request but nothing seems to be working.
App Route:
@app.route('/Exercise', methods = ['GET'])
def exercise():
test = request.form["title"]
print(test)
if test != None:
info = select(["*"],"Exercises",["Name"],"And",[test])
print(info)
return render_template('exercise.html')
HTML:
<body>
<form>
<h2 class="head" id="name" name="title"></h2>
<p class="lead">Details</p>
</form>
</body>
<script type="text/javascript" src="static/js/exercise.js"></script>
</html>

Ok so thanks to PRMoureu I discovered I needed to make the called url contain the field I wanted to get with flask. Example below: window.location.href = "/Exercise?title="+name;
Thanks for the help much appreciated

Since you're supporting the GET method only try accessing your title key like so:
request.args.get('title')
instead of test = request.form["title"] as this is the way you would access the title key in a POST method.
Hopefully that helps!
